TIRE SPREADING MACIINE Filed sept. 5. 1929 Patented July 5, 1932 JAMES L. PESHETTEOF PERU, 'NEW' YORK TIRE i, SPREADING MACHINE Application led september l`his invention relates to machines for spreading the casings of pneumatic tires for inspection preliminary to repair and replacement of the inner tube therein, and' has for its object the provision of a machine of the character stated having a base member to support a casing for inspection and including hook members to engage the beads of the-tire, one of said hook members being pivotally l mounted on a pivoted arm for spreading the casing to eXposeits interior.

A further object of the invention isithe provision of means for adjusting onefof the hooks, above referred to, toV adjust the e mechanism for use of variousl sized tire casings. y ,l

The invention will be described herein- Y after and will be found illustrated in the accompanying drawing, in which Figure 1 is a top plan view of the improved tire spreading machine, Y

Figure 2 is a side view in elevation, Figure 3 is a longitudinal sectionalview on a. plane indicated by the line 3-3V of f Figure 1,

Figures 4 and 5 are transverse sectionalv views on planes indicated by the lines 4 4 and 5-5, respectively, and

Figure 6 is a view similar to F igure 3 showing the machine in position spreading a tire casing illustrated in transverse section.

Referring to the drawing in which similar reference characters designate corresponding parts in the several views, the improved ""i machine comprises a. base plate 1 that is the casing A, .the terminals of the rod at the V extremities of the VU-shape having'loops 9 f thereonthrough which the pivot pin 5 is inserted to secure the hook member 6 in pivoted relation withthe ears 3 and the base member n 5, 1929. Serial No. 390,561;

' PATENT OFFICE M I 1.-. 10 indicates other spaced ears havingans gularly related feet 11 thatare secured to the base plate 1. Between the ears lalever arm 12 is pivotally mounted on a pivot pin'r 13, and secured to said arm 12 is a plate. 14 having Yitsends 15 perpendicularly related to the intermediate portion of the plate and providing spaced ears having alined openings 16 to receive a pivot pin 17 to pivotally support a hook ymember 18 similar in construction to hook member 6, including loops 19 to engage the pivot pin 17, 20 indicating pins secured through transverse openings in the pin 17 to hold the loops 19V on the pin.V The hook 18 is provided tovengage the bead a of the casing A and by turning the arm 12 on pivot-pin 13 the casing will be opened, as shown in Figure 6, for inspection. Y

By providing a plurality of alined openings 4 for the .pivot pin 5 it will beapparent that the hook 6V may be adjusted so that the machine may operate on casings of varying sizes.

Furthermore, as shown in Figures 1, 2 and `v vide a compact structure for storage of the machine' when not inuse. 1

I claim baseplate adapted to supporta tire,'ears on te A tire spreadingmachine, comprising a said base having a' plurality of alinedropen- Y ings, a hook member, means to adjustably pivot said hook member in alined openings in said ears, a lever arm pivotally supported on said lbase plate, and a hookmember pivotally mounted on said lever arm, said hook mem-V bers being adapted to engage thefbeads of the tire and tospread it by actuation of said lever arm'on its pivot, said hook members being formedfrom U-shaped members-and the lever being movable within said hook members for storage of the machine.
